Why Radiologists Make Mistakes

Decent Essays

RADIOLOGY: It’s not so black and white, more 50 shade of grey.
The diagnostic imaging process involves two individual parts. In breast imaging (mammography), conventional radiography and Ultrasound scanning (USS), there is the technical function of image acquisition by the radiographer followed by the diagnostic task undertaken by the radiologist. A poor quality image impedes adequate reading which may lead to mis-diagnosis.
For fluoroscopic procedures such as barium enemas, cardiac imaging and the examination of blood supply (angiography), the radiologist is involved in acquiring the individual images that comprise the investigation in addition to radio-diagnosis.
However, with Computerised Tomography (CT) and Magnetic Resonance Imaging …show more content…

Research into radiological error has consistently demonstrated differences in radiological performance, and studies of radiological error also report significant rates of both intra and inter observer variability, with radiologists making both false positive and false negative decisions1. Approximately 4% of radiological interpretations contain errors2. The pertinent question is why do radiologists make mistakes? There are several reasons why radiologists are sued: Observer error (search, perception and cognition), failure to suggest further imaging, and failure to report any results in a timely …show more content…

Unfortunately, some conditions can have similar appearances (Table 1), whilst some “abnormal” appearances are in fact normal variants particular to that patient.9

Apart from mis-diagnosis, failure to pass on results is also a factor in medical malpractice cases. Records from medical insurance companies indicate that the second most common cause is failure to communicate the results of a radiological examination10. Such communication failure may be a factor in 80% of cases11. Although a radiological report is generated by the imaging facility and should be sufficient but in some instances this report may not be received or read. Hence, the radiologist becomes part-culpable in any lack of intervention.

Research by Berlin also stresses the medico-legal risk of a vague radiology report.12 He reviewed cases that involved a delayed diagnosis of malignancy which led to litigation. The reports were not inaccurate, but each of the referring physicians testified that if the radiologists had emphasised their opinion more weightily they would have acted much more readily.
